% Manual Page macros

% \begin{manpage}{Title}{Module}{Version}  % see an example, all will be clear
%                 % latex supplies the current date if no \date{} is specified
% \end{manpage}   % end of manpage environment
% \variable{#1}  (e.g., \variable{int foo}) % with \medskip added
% \variable*{#1} (e.g., \variable*{int bar})% no extra spacing
% \function{#1}  (e.g., \function{void demo(int dummy)}) % with \medskip added
% \function*{#1} (e.g., \function*{void demo(int dummy)})% no extra spacing
% \subtitle{#1}  (e.g., \subtitle{AUTHOR}) % fit in the same line if possible
% \subtitle*{#1} (e.g., \subtitle*{AUTHOR})% always break a newline
% "#1"           (e.g., "dummy_variable")  % argument is in italic&unbreakable
% \separator		% draw a thin line to separate subtitle from the text
% \header{#1}{#2}{#3}	% in case you want to have a header and 
% \footer{#1}{#2}{#3}	% a footer outside of the manpage environment
%
% In the \function macro, data types and their dummy arguments are separated
% by a space. So if you have a function like "int f(const int n)", you should
% document it as \function{int f(const~int n)}.  The argument n is optional.
% In the \subtitle macro, two lines of text may be divided by "\\".
%
% The following characters (control-sequents) are defined (or redefined) as:
%
% \" --- print the double quote character ("), use $\ddot{\rm#1}$ for accent
% \~ --- defined as $\sim$ being raised 0.6ex, use $\tilde{\rm#1}$ for accent
% \* --- the same as $\ast$
% \< --- the same as $\langle$
% \> --- the same as $\rangle$
% <  --- the same as $<$
% >  --- the same as $>$
% _  --- the same as \_,  use $\sb{#1}$ for subscript (see TeXbook pp. 135)
% +  --- the same as $+$
% |  --- the same as $\mid$
% ^  --- {\small $\wedge$} being raised 0.6ex, superscript is now $\sp{#1}$
% "  --- the same as {\tt "} when outside of the manpage environment,
%        otherwise use \" instead

\newdimen\funindent \funindent 0pt % indentation for function/variable entries
\newdimen\argindent \argindent -1pt % indentation for function arguments

% when \argindent >= 0pt, subsequent lines of arguments have fixed indentation
% i.e., \argindent (e.g., 3em).  See the following example:
%       int foo ( int x, int y, int w,
%             int h, char a, char b,
%             char c, char d )
%
% when \argindent < 0pt (value doesn't matter), arguments are auto-indented:
%       int foo ( int x, int y, int w,
%                 int h, char a, char b,
%                 char c, char d )

% \tableofcontents and \chapter macros are also modified in manpage.sty.
% The standard LaTeX \tableofcontents couldn't handle \chapter* correctly.
% In the table of contents each manpage has the same indentation as a section.
% Chapter titles have smaller font and they are pushed to the right margin.

% > From: Vick Khera <khera@cs.duke.edu>
% > one more thing you may like... we have this cprog.sty style
% > (formatting of C programs, by \'Eamonn McManus <emcmanus@cs.tcd.ie>)
% > that lets you place C, C++, Pascal, and Modula-2 source code in your
% > LaTeX source directly. no more verbatim mode, which i think is ugly
% > for C code.  just be sure to include it *before* you include manpage.sty
% > or things break.  i don't know why, but i can live with it:
% > \documentstyle[cprog,manpage]{report} will do the trick. then just replace
% > those pesky \begin{verbatim}\end{verbatim} with \begin{cprog}\end{cprog}
% > and it looks much better.  i also like to put after the \documentstyle
% > the command \let\ctextfont=\sf so the code is typeset in the \sf font
% > to differentiate it from normal text.
% (you may do the same with \let\ccommentfont=\sl and \let\cstringfont=\sf)

% the latest versions of manpage.sty and manpage-sample.tex are saved
% at the clarkson archives, sun.soe.clarkson.edu (128.153.12.3).
% the files are in /pub/latex-style directory for anonymous ftp.
% cprog.sty should also be there.  check it out.

% If you make any improvements, I'd like to hear about them.

% STOP STOP STOP -- comments end here :-(
